,The present invention seeks to meet all of theforegoing conditions in aneffective and economical manner by developing the tank storage for the washout Water andreilling Waterof aboilerwashing systemin the form oi' a plurality of SGparateandfindependent units of a .construction andsizge that can be standardized so that'required'capacity Will bel met selectingthenumber of units necessary to` equal the total capacity required. The invention includes the arrangement,

equipment. and relation of the. severalcunits Y of the tankstoragefwhereby they will act largelyas a single unit in thematterof in,- Y

they are vall-infuse, and whereby each indi! vidual unit,` or any numberoftheunits lessk than thev Whole, may be utilizedlt'o the excluT sionot ther remainder, and any one or more' ofV the, units maybe temporarily isolated and emptied beforecleaning or repair. 1`
